'Appllcation filed October 27, 1915. Serial No. 58,144.

- To all whom it may camera:

cally to'a metal beam or strip designed to be employed asa furring strip, or the like.

The primary object of the invention is to provide a structural member whichis especially designed foruse as a furring strip, being adaptedto be secured to wooden joists, beams,studding and the like and to have ceiling plates, wall plates, flooring, or the like, nailed thereto.

A further object is to provide a sheetmetal structural member of the character.

mentioned which is possessed of unusual strength and rigidity.

. ith these and other objects in view, the invention resides in the features of construction which will hereinafter be fully described, reference being had to the accompanying drawings, forming a part of this specification, in which-- Figure 1 is a perspective view of the invention; Fig. 2 is an end elevation of the two metal strips of which the invention is comp osed, the same being shown separated; and

ig. 3 is an end elevation of a slightly modi-' fied form of the invention.

The device composing the invention comprises two similar sheet metal strips adapted to be rigidly secured together by any suit- 1 able means, as by rivets. Each strip comprises a horizontal base portion 1, a substantially vertical web ortion 2 and a horizontal head portion 3, said web portion being interniediate said base-portion andsaidlhead Q head and le portions are formed of a double thiclmess o metal, the strip being doubledportion. Said head is supfiorted ugon'a leg portion stwhich is incline outwar ward at an angle to the web portion 2. Said gether I plaits and'forming andupr sheet-metal and coiislstmg of ahead, a base,

back upon itself from the lateral edge of the head portlon and having its edge terminatmg adjacent to or slightly below the angle formed at the juncture of the leg with the Y Web. When the two strips are secured toether the portions of the web members adacentto the folds closely abut against each other and form a yieldable joint in which the points of nails driven between the strips are received and yieldingly gripped.

A longitudinal plait or fold 5 is formed in the web portion 2 for stifi'ening or strengthening said webportion In forming said plait the metal ,is. flexed and reflexed upon itself either in the open loop-like manner illustrated at 5 in Figs. 1 and 2 or in the close-pressed manner shown at 5 in Fig. 3'. Said plait ispreferably formed slightly below'the'middle of the web, as shown.

The two strips of metal are secured todirected through the web portions above the 5. .The two leg portions 4 meetat their lower' ends and then divergently mcline outward to constitute a longitudinal V-shaped groove-or'channel 7. -When, in attachingpla'tes or the like to the member, nails are directed into" said groove or channel 7, said nails are. guided'by the walls of the latter into-the interstice between the webs, and, penetrating between said webs, are firmly gripped by the latter. 'What is clalmed is- 1. A structural memben composed of web to web, as. by means of rivets 6 sheet-metal consisting of a base, a horizontal head, and a substantially vertical web, said web being composed of two-thicknesses of metal each of whichsis flexed and reflexed upon itself to form a longitudinal fold, said two thicknesses being securedtogether' at points intermediate said fold and said head a y'ieldable joint adjacent to the folds'for yieldingly grippingnails driven between said two thicknesses.

2. A structural 5 member' -composed of and a web connecting-saidfhead. and said said meeting composed erx 'oattached members disposed back to back, each the points of nails driven between said mem web being flexedand reflexed upon itself to bers are yieldingly gripped. A 10 form a longitudinal plait' intermediate its Intesnmony whereof, I'aflix my signature head and basexportions, said plaits being disin presence of two subscribing wltnesses.
